Abstract: The paper is involved in
larger valve recession that appeared in the three-cylinder and 90 diesel engine
after it was given a reliability test.The valve wore over its limit,causing the
problem.With CFD Emulation and analysis to the cooling system of the diesel
engine,this above problem has been solved effectively.
Keywords: Diesel;Abrasion;CFD
Emulation;Cooling
